What is True 4K? What about resolutions: 2160P, WUXGA, 1080P, 720p?
Consumers Technology Association says a true 4K or UltraHD must deliver at least 8.3 million distinct pixels while projection. It means the image you see on the screen has to have 8.3 million active pixels. If it doesn’t, your 4K projector is no more true 4K; instead, it will be considered as a partial 4K projector. Therefore, for true 4K, make sure your projector is four times the 1080p Full HD resolution.
Now, the resolution: 2160P, WUXGA, 1080p Full HD, and 720p HD
- It ensures the resolution 3840×2160 and 4096×2160 Horizontally and Vertically of pixels, respectively.
- You get around 8.3+ million distinct pixels, the total number of active pixels on the screen.
- The 2160p is also known as 4K, Ultra HD, Ultra-high-definition, and UHD.
- Mostly Projectors and TVs adopt it.
- It ensures 1920 horizontal and 1200 vertical pixels of resolution.
- The total number of distinct pixels on the screen you see is around 2.3 million.
- It stands for Widescreen Ultra Extended Graphics Array.
- Devices such as projectors and monitors utilize it.
- It offers 1920 horizontal pixels while 1080p vertically.
- The 2.1 million distinct pixels can be seen on a screen.
- It carries other names, too, such as Full HD and FHD.
- Generally used by Projectors, TVs, and monitors.
- It boasts 1280p pixels horizontally and 720 pixels vertically.
- The total number of distinct pixels reaches 0.92 million.
- People name it HD and High Definition.
- Projectors, TVs, and other similar devices utilize this resolution.
What is XPR technology in 4K projectors?
More precisely, DLP XPR technology. It comes from Texas Instruments and refers to pixel-shifting technology. Moreover, a projector adopts it to achieve 8.3+ million distinct pixels with true 4K resolution. Now you might ask, how does it do it?
As you know, the DMD chip, utilized by a projector, offers a certain number of native pixels. If the DMD chip is equipped with 4K resolution and 8.3 distinct pixels, then consider yourself and your projector to be at a safe place. On the contrary, if it is partially 4K and offers resolutions like 2716×1528 pixels (0.66″ chip) and 1920x1080p (0.47″ chip), a projector struggles to achieve true 4K resolution and, of course, 8.3 million pixels.
This is where the XPR technology takes place; it doesn’t care about the DMD chip’s native pixels and helps a projector achieve the optimum true 4k resolution with 8.3 active pixels. In other words, XPR technology doubles the native 2716×1528 resolution of the 0.66″ DMD chip and quadruples the resolution 1920×1080 of the 0.47″ DMP chip. That’s why it is pixel-shifting technology.
The difference: XPR technology Vs. 4K enhancement technology
Even though both are pixel-shifting technologies, their mechanisms are entirely different and thus produce different projection results. However, XPR technology is for only DLP projectors, while other projectors utilize 4K-enhancement technology. So let’s figure out the real difference between the two.
XPR: What is XPR Technology?
Regardless of the DMD chips’ native resolutions, a projector with XPR technology still achieves 8.3 million pixels with true 4K resolution by doubling or quadrupling their native resolutions, such as 2716×1528 pixels of 0.66″ DMP chip and 1920×1080 pixels of 0.47″ chip. Moreover, it is Texas Instruments’ pixel-shifting technology.
4K-Enhancement: What 4K-Enhancement technology?
The 4K-Enhancement technology can’t produce the required 8.3 million distinct pixels; instead, it has the capability of producing 4.1 million pixels by doubling the native Full HD resolution (1920x1080p). As a result, you have only half the number of 8.3 million pixels.
Moreover, as far as its mechanisms is concerned, the 4K-Enhancement technology struggles to generate true 4K 8.3 million pixels because of its slower pixel shifting speed.
FAQs: Commonly asked questions about 4K projectors and their technologies?
When true 4K HDR is concerned, you’ll need a 4K Blue-ray player, an excellent native 4K HDR projector that offers 3840*2160 at 60 Hz, a 4K supported HDMI cable (HDMI 2.0 or above), and of course, 4K HDR videos or movies.
It’s is true that most HDMI cables can’t support Ultra HD HDR resolution. Therefore, you’ll have to make sure that the HDMI cable you choose is certified for 4K at 60Hz fps. The HDMI version you should go for is 2.0 and above, such as 2.0a/b.
Of course, you can, as long as it is a true 4K projector. However, you’ll need compatible HDMI cables according to the content being streamed. For example, your Netflix content protected by HDCP 2.2 requires the same 2.2 HDCP compatible HDMI cable.
Buying Guide: How to choose a 4K projector?
No doubt buying a projector depends on many factors and your preferences; it also boils down to your budget. Since cheap projectors cant offer 4K projector resolution, you’ll have to spend at least 2000 dollars for a true 4K projector with HDR support. However, projectors that partially support 4K resolution can be bought for under 500 bucks and even 200. If you don’t believe it, check out my list of the best 4K projectors under 200 and the best Ultra HD projectors under 500.
Anyway, In this buying guide, we’ll look at the primary considerations of a 4K projector.
1. Throw Distance: What is better for your 4K projector: short or long?
The throw distance determines the optimal range between the projector and the screen to create an optimum image size, though different projectors offer different screen sizes with their recommended throw distances. In other words, throw distance is just the range between your projector and the projection screen.
However, mid-range projectors, such as projectors under 1000, offer long throw distances compared to expensive projectors. Short throw projectors don’t require long distances for a big picture. Therefore, short-throw projectors are considered the best for small rooms. When the recommended projector to screen distance is concerned, you can place your projector from 4.5 feet to 8 feet away from the screen to project a 100-inch picture.
On the other hand, you have long throw projectors known for projecting a big image from any distance. Therefore, a long-throw projector offers better and much-improved flexibility with more installation options than a short-throw projector. Moreover, you don’t have to spend much on the types of projectors. The recommended throw distance for large rooms is from 8 feet to 13 feet for 100 inches projection size.
2. Lighting conditions
Everyone knows projectors are well-suited for dark locations; otherwise, one will end up watching low-quality images with blurriness and distortion on the screen. Modern and expensive 4k projectors offer different custom brightness modes and levels to maintain the image quality up to the mark according to the light conditions. However, if you don’t want to buy expensive projectors, make sure you have better control over your room illumination.
Moreover, I suggest you choose any dark location or place with fewer windows.
3. Display technology
When it comes to modern and popular display technologies, you have two types of displays to choose from, DLP type and LCD type. The DLP technology means a DLP chip containing millions of mirrors, responsible for the projector’s resolution by its intricacy and size.
For example, most 4K projectors use a DLP chip for providing true 4K by achieving the ideal number of pixels, 8.3 million pixels. In addition, such projectors use an advanced color wheel called ‘RGBRGB”, hex-color wheels instead of ‘tri-colored wheels. It helps the wheel spin faster as its primary colors, “RGB,” can get two segments.
Therefore, the display technology of a projector leans more toward DLP than LCD. However, LCD has some advantages or say DLP has some disadvantages.
Unlike millions of mirrors, LCD utilizes a few mirrors in order to project light. Therefore, it is very common for LCD projectors to show saturated projection on the screen while using projection applications. However, utilizing small LCD panels deliver a more bright and much jaggier image compared to DLP.
Having said that, I recommend a DLP type display when 4K projectors with true 8.3 million distinct pixels are concerned.
Since the article is about 4K projectors, we should stick to the 4K resolution, too, 3840x2160p or 4096x2160p. Again, it’s the matter of counting the total number of pixels on the screen, totaling 8.3 million distinct pixels.
The only noticeable point here is to avoid pixel-shifting technology known for generating duplicates of any projected frame. That’s why most projectors struggle to project a true 4K image on the screen. Unfortunately, it isn’t easy to figure out whether it is true 4K or generated one, as it happens at lightning-fast speed with zero flickering and side effects.
On the other hand, true 4K projectors without any marketing terms only offer up to 8.3 million active pixels per frame. So avoid projectors using technologies, such as 4K enhancement and pixel shifting.
